SDA 9361
1: external references on V_REFP, V_REFH, V_REFL have to be applied
(in this case BANDG4OFF must be = 1)
BANDG4OFF: Bandgap 4 V Off
0: internal bandgap reference is used for V_REFP
1: external reference on V_REFP (4 V) has to be applied
The Status Byte includes the following bits:
HPON VPON CON
-
-
-
-
PONRES
HPON:
protection on
0: normal operation of the line output stage
1: high level on input HPROT has switched off the line
VPON:
V-protection on
0: normal operation of the vertical output stage
1: incorrect signal on input VPROT has switched off the line
CON:
Coincidence not
0: H-coincidence detected
1: no H-coincidence detected
PONRES:
Power-On-Reset
0: after bus master has read the status byte
1: after each detected reset
Note: PONRES is reset after this byte has been read.
2.5.5 Explanation of Some Control Items
D/A
This item controls directly a 6 Bit D/A Converter at the output D/A that can be used for
general purpose.
Start Vertical Scan
If enabled (SSE = 1) this control item defines the start of calculation of the vertical saw-
tooth, the east/west parabola and the vertical function required for the vertical modulated
output HD.
